Trace node producing jagged edges and weird normals 2024年4月15日11:49

Sorry, I forgot to include the .hipnc file. Here it is.

Trace node producing jagged edges and weird normals 2024年4月15日11:48

Hi!I'm having some issues with polyextruding a trace node:

Problem #1

I have a 2D logo where I used a trace node and then polyextruded the letters to create a logo intro. I noticed the trace node created quite a lot of points, so I used the resample in the trace node to lower the points and smooth out the curves, but the edges are still jagged. Is there a way to have smooth curves so the letters look like they do in the logo?

Problem #2

The front of the polyextrude looks really weird. It looks like brushed metal in some places and isn't smooth. I tried a normal node and played around with a low cusp value (around 10) and it seems to fix it on the faces, but also kinda looks too angular and makes the light hit it differently, so I'm wondering if there is a better way to do all of this to get rid of the weird artifacts on the faces of the polyextrude?

Hipnc file attached, as well as screenshots of the issue, and also the logo png files to load into the trace node if needed.


Toruses copied to points fall as one object in RBD sim 2024年4月12日22:20

Thanks so much to both of you for the two solutions!

I do like the bullet solver with the RBD configure node. It seems like there are lots of good presets like wood, glass, concrete, etc. I will use that from now on.

I was just using the shelf tools for RBD and just choosing "RBD hero object" for the rings, so maybe I did something wrong. I'm still a little confused on when to use RBD and when to use bullet. I tried to use the bullet and just add a pack node before I sent the geo to dops but it didn't work right. I'm still learning. I'll google some more tutorials about RBD stuff in Houdini 20 so I can memorize the workflow and not rely on the shelf.

I added a pop noise into a multisolver to add some variation in how they fall, and it looks great!
Obviously the scale is huge, so they are falling like very large rings. Does the bullet solver work well at smaller scale (so they can bounce around more violently like little plastic rings that don't weigh very much? I know things like FLIP fluids don't work as well at very small scale so I was wondering if the bullet solver is the same.)

thanks for the help!
